Scientist here, just a bit of a pet peve here. This isnt a good answer. Lead can form through normal processes (stellar)and doesnt require radioactive decay as its main source. In fact most lead on earth existed when the earth was formed.

My thought, not a good answer. Supernova nucleosynthesis can produce lead.
I'm curious, did you see my reply on Takei's post directly, or from my page or something?
@freemo @georgetakei
I'm following George on Mastodon and just scrolled through the replies to this particular post, because I also felt the answer left much to be desired and was curious what others might have to say on that.
Thts interesting since Universeodon recently suspended our whole server in retaliation for me calling our their new moderator for abusive practices. So wouldnt have expected my replies to show.
@freemo @georgetakei
Seems so. Looking at the posts' page on George's server directly your answer appears to be missing. https://universeodon.com/@georgetakei/111936656496446905
